Letters Patent No. 107,820, dated SeptemberZ?, 1870.

i The `Schedule referred to in these Letters Patent and making partofthe same.

Be it known 1 that'LOARL `Flnnnnrcn ScHLicK- invented certain" new'anduseful `Improvements in riads, of .which thefollowng is afull4 clear,and exact descriptlomreference being` had tol the accompanywhich-flFigure 1' represents a sectional side yiew, takenas indicated bytheiline a; x,liu `igs. 2 -and `3, of a machine constructed inV'accordance with my i'n'vention;

Figure 2 is an end-or rear elevation of said machine;

, Figure 3, asectional plan, taken as indicated. by the line y yingsland 2.`

i This improved machineis more especially desigmdT for the working offricestones, and 'haslfor its object r.[ `he invention consistsinvariouscoinbiiitons of devices, including intermittently-acting` picks or cut'diiierently adj ustable arrangements of theparts of the In theaccompanying `drawingvthe machine is repf leveling action onfthe stone,but various dresses may be made and different profiles formed bysuitably adjusting the fa-lhboth as regards-extent andorder,

or cutters, and feed of thestone while being dressed.

In said drawingl A represents a bed or` foundation, on which is mountedthe frame B and B of the machine.` l C is a rail track, resting looselyon transoms l), and made capable of adjustment laterally by means'- of ascrew,t, and connecting-shackle b, which latter is.. attached, by avertical pivot, to the rail track, whereby the latter is capableof beingswiveled horizntally on saidupivot of the shackle.

This double adjustment of the rail track provides for both special andgeneral yadjustment of the stone undery the pickers or cutters, thelateral adjustment by the `screw a providing for the adjustment of thestone to vary its lines of cut as effected by thc pick-v ers or chiselsoperating at distances apart, and whereby the stone may, by repeatedtravels of it under the cutters, be dressed over its entire surface. l l

The stone is supported on a truck or carriage, E,

frd thereon by any suitable means or application of' power.. V-F is thedriving-shaft that operates the cutters, and which .may be revolved byany suitable means. On this shaft are arranged andy secured, so as torotate with it, any desired number of toe-carriers, G,

i lying side by side, andi armed with toes or lifters, d,

differently set or disposed, so that they will act suc` cessively,either in regular or irregular order, ou

sledges H, loose upon a rod or shaft, I, to raise the front portions .ofsaid sledges, which carry picksV l chisels, or fcutters, e, and so thatwhen said sledges are released from the toes they will deseendby"whichcarry them may have their' drop varied rela# tively to each other;or certain of them be worked in vmore rapid spccession than the others,to secure dierent depthsor extents of cut. A beam, J, adjustable up ordown the portionB of the frame, is here shown as serving to arrest andregulatej'the striking action of the sledges, so that the cutters arerestrained "from entering beyond a given depth into the stone, andwhereby the sledges Y are retained in proper position for the liftingaction of the toes on them.

This beam may be of any desired configuration on its upper surface tosecure a varied, action to thc sledges and their cutters relatively toeach other.`

The slide or truck E, which carries the stone, may be run either forwardor' backward under the picks` or cutters as'v the stone is operated onby the latter.

To adapt the machine to operate on dilferent thicknesses of stone, andto do different kinds of work, and

`to adj ust it generally and specially, in certain respects,

to different kinds of stone or qualitiesl of material being worked, theshaft I, on which the sledges H rock, and the revolving shaft F, whichcarries and rotates with it the toe-carriers G, and their toes (l, arehung in boxes,

carried by slides K, arranged s0 as to be capable of up-and-downadjustment on the posts B of the frame by means of scrcws, f, made to tboxes in the slides within the posts, that may have slots, g, in them,for the guidance of the slides and their connection with theadjusting-screws f. lhe boxes h, that carry the shaft F, are also' madeseparately adjustable up and down the slides AK by al dovetail orsliding t of said boxes within the slides K,,andadjustment of the sameby screws t, or other .suitable devices.

By this latter adj nstment,l the toes d are made to act sooner or later,and with a longer or shorter throw sliding boxes h, which carry therevolving toes or shaft operating the same, with the slides4 K and thesledges H, cssentallyns described.
